Angel/ Cherub Sweet Sixteen cake

I need an idea for an angel decorated cake. I have small ceramic angels that I can put on top of each cake. I am doing 6 individual double layer cakes. They are going to be 2-6", 2-8", & 2-10". The colors are going to be turquoise and kiwi green.

I was thinking of doing alternating "ropes" in each color then a border still thinking about it though.

Maybe you can add some feathers to the back of the bigger cakes. You can get those at a micheals or hobby lobby, that would really give the soft touch of an angel. Just a thought. Also maybe if the feather is to much, you can lay white feather boas around the table just to give it a soft touch. Good luck and yes the colors sound perfect
